My TT Moment in constant high winds (35 -45 mph.) was BREEZY even with a 1 ft. high snow wall around the front and clothes laid on the floor level netting.
Had there been blowing snow the spindrift would have come right inside the tent.
The Skyscape, being a hybrid (partial) double wall, may be a bit warmer and W/O the Moment's ground level netting may be better suited to keep out more (but not all) spindrift. But you DON'T want to use the Skyscape's optional porch on cold nights.
I think the Skyscape could be improved with TarpTent-like closeable peak vents.
